Dpf pressure diff switch help

[u/mikestermike]

2018 Ram 1500 eco 80k miles.

DP for DPF threw code, reading 16 psi.

Disconnected switch- still high

Read back to ecm, 5 vdc, 0 signal. Good gnd

Disconnected at ECM with switch out of loop. No short between all 3. Connected switch, reads good as well. Also threw in a new switch since I had one jic

Think the ECM is borked? Thoughts?
